ENGLISH USER MANUAL
GENERAL INSTRUCTIONS
Specifi c warnings and cautions to inform about potential damages to people and machine are shown below.
DANGER!
Always disconnect the power supply cable when the machine is not in use, before performing maintenance
procedures, before replacing the brush/pad-holder and before opening any access panel.
This machine must be used by properly trained and authorised personnel only. Children or disabled people cannot
use this machine.
Do not wear jewels when working near electrical components.
Do not work under the lifted machine without supporting it with safety stands.
Do not operate the machine near toxic, dangerous, fl ammable and/or explosive powders, liquids or vapours.
WARNING!
The machine power supply cable is grounded and the relevant plug is grounded too. In case of machine malfunction
or breakdown, grounding connection reduces the risk of electric shock.
The power supply cable plug must be connected to an appropriate outlet, which is grounded according to law in
force.
Improper connection can cause electric shock. Consult a qualifi ed technician to make sure that the outlet is properly
grounded.
Do not tamper with the power supply cable plug. If the power supply cable plug cannot be connected to the outlet,
have new grounded outlet installed by a qualifi ed technician, according to the law in force.
Before connecting the power supply cable to the electrical mains, check that frequency and voltage, shown on the
machine serial number plate (1), match the electrical mains voltage.
Do not unplug the machine by pulling the supply cable. To unplug, grasp the plug, not the cable.
Do not handle the plug or the machine with wet hands.
Turn off all controls before unplugging.
Regularly check the power supply cable for damages, cracks, cuts, etc. If the power supply cable is damaged, replace
it immediately.
To avoid any risk, if the power supply cable is damaged, contact Alto Service Center or a qualifi ed technician.
Do not pull or carry the machine by the power supply cable and never use the power supply cable as a handle. Do not
close a door on the power supply cable, or pull the power supply cable around sharp edges or corners. Do not run
the machine on the power supply cable.
Keep the power supply cable away from heated surfaces.
To reduce the risk of fi re, electric shock, or injury, do not leave the machine unattended when it is plugged in.
Disconnect the machine from the electrical mains when not in use and before performing maintenance procedures.
Always protect the machine against the sun, rain and bad weather, both under operation and inactivity condition.
Store the machine indoors, in a dry place.
Do not allow to be used as a toy. Close attention is necessary when used near children.
Use only as shown in this Manual. Use only Alto's recommended accessories.
Take all necessary precautions to prevent hair, jewels and loose clothes from being caught by the machine moving
parts.
Do not leave the machine unattended without being sure that it cannot move independently.
Do not use the machine on slopes with a gradient exceeding the specifi cations.
Do not use the machine in particularly dusty areas.
While using this machine, take care not to cause damage to people or objects.

USER MANUAL
ENGLISH
Do not bump into shelves or scaffoldings, especially where there is a risk of falling objects.
Do not put any can containing fl uids on the machine.
The machine working temperature must be between 0°C and +40°C.
The machine storage temperature must be between 0°C and +40°C.
The humidity must be between 30% and 95%.
Do not use the machine as a means of transport.
Do not use the machine on slopes with a gradient exceeding the specifi cations.
Do not allow the brush/pad to operate while the machine is stationary to avoid damaging the fl oor.
In case of fi re, use a powder fi re extinguisher, not a water one.
Do not tamper with the machine safety guards and follow the ordinary maintenance instructions scrupulously.
Do not allow any object to enter into the openings. Do not use the machine if the openings are clogged. Always keep
the openings free from dust, hairs and any other foreign material which could reduce the air fl ow.
Do not remove or modify the plates affi xed to the machine.
If the machine is used according to the instructions, the vibrations are not dangerous. The machine vibration level is
less than 2.5 m/s
2
(98/37/EEC-EN 1033/1995).
This machine cannot be used on roads or public streets.
Pay attention during machine transportation when temperature is below freezing point. The water in the recovery tank
or in the hoses could freeze and seriously damage the machine.
Use brushes and pads supplied with the machine and those specifi ed in the User Manual. Using other brushes or
pads could reduce safety.
In case of machine malfunctions, ensure that these are not due to lack of maintenance. If necessary, request
assistance from the authorised personnel or from an authorised Service Center.
If the machine
does not work properly
is damaged
has water or foam leaks
has been left outdoors exposed to bad weather conditions
is wet or has been dropped into water
turn it off immediately and contact Alto Service Center or a qualifi ed technician.
If parts must be replaced, require ORIGINAL spare parts from an Authorised Dealer or Retailer.
To ensure machine proper and safe operation, the scheduled maintenance shown in the relevant chapter of this
Manual, must be performed by the authorised personnel or by an authorised Service Centre.
Carefully read all the instructions before performing any maintenance/repair procedure.
Do not wash the machine with direct or pressurised water jets, or with corrosive substances.
The machine must be disposed of properly, because of the presence of toxic-harmful materials (electronic
components, etc.), which are subject to standards that require disposal in special centres (see the Scrapping
chapter).
